Crime Branch officers have arrested a man with two deadly weapons and six live cartridges on Thursday evening.

Sources told mid-day that the accused Salim Shahabuddin Khan alias Sallu, apparently a police informer who works as a caretaker at a real estate office in Goregaon East, had been threatening and trying to extort money from a city-based builder who had approached the Mumbai police and submitted a written complaint. The police machinery became active after the complaint was submitted recently and the numbers of Sanjay and the builder were kept on surveillance, said the source.
